IMPROVEMENT lN CARD-BOARD DRIERS.

Specification forming part of Letters Patent No. 128,455, dated July 2,1872.

To all persoas to whom these presents may come:

Be it known that I, EDWIN F. BAILEY, of Ashland, of the county ofGrafton and State of N ew Hampshire, have invented an Improved(lard-Board Drier; and do hereby declare the same to be fully describedin the following specification and represented in the accompanyingdrawing, of which- Figure 1 is a side elevation, and Fig. 2 a transversesection of it. Fig. 3 is a vertical and longitudinal section takenthrough its heating apparatus.

The purpose of the drier is to effect the desiccation of sheets ofpasteboard, card-board, or other articles of lik character, and in doingthis it accomplishes what the apparatus represented and described in theUnited States Iatent N o. 68,146, granted August 27, 1867, to me, wasintended to do. My present invention may be termed, in some respects, animprovement with reference to the patented one; and it consists of a newarrangement of heating-pipes with reference to the card-board carriersand their supportingfralnes, whereby the heat radiated from theheating-pipes is thrown upon opposite sides of each sheet of board at011e and the same time, and to better advantage, than by the dryingapparatus as heretofore patented by me. It further consists in thebuilding as provided with openings iu its side or sides, in combinationwith the card board carriers as provided with front boards to close suchopenings and to regulate the ingress of air passing through suchopenings and across the cardboard or its carriers.

In the drawing, A denotes a close box or building, formed asrepresented, and provided with a ventilator, B, placed at the middlepart of the upper portion of the said box or building, there being tosuch ventilator a valve, C, to be actuated by a rope, D. In each of thetwo opposite sides of the box is a series of long rectangular openings,E, for reception of the card-board carriers or frames G, a top View ofone of them being given in Fig. 4, and an edge view of it in Fig. 5. Itconsists of a rectangular frame, a, furnished with a drawer-front, b,and a series of support-wires, c c c, or the equivalent thereof, allbeihg ara ranged as shown. Connected with the said openings of each sideof the box is a frame,

F, provided with inclined guides or rails r for supporting the severalcard-board carriers G, those in each vertical row being parallel orabout so -to each other, and inclined to the horizon and upward yfromtheir respective openings E in the side of the building. Vhen eachcarrier is fully in place in the supporting-frame F the front board bcloses the aperture E for its reception. By drawing backward, however,the carrier, the opening may be more or less opened for the passage ofair into it and over the card-board when supported on the carrier. Thehot-air or steam pipes for heating the card-boards are shown at H asarranged in a serpentine course, so as to pass both over and under eachof the carriers, there being a series of pipes running over and acrosseach carrier, and also between it and the next one directly over it, allbeing as shown, and so connected that steam or heated air, when let intothe pipes, may be caused to circulate through them, so as to cause themto radiate heat both to the upper and under sides of each card-boardcarrier. The air let into the carrier-openings E will flow up betweenthe carriers, and, receiving the vapors passing from their card-boards,will convey it to and into and through the ventilators, the enteringcurrents of air being gauged by more or less pulling backward themouth-boards b of the carriers.

My present construction of card-board drier enables me not only to heatthe card-boards to better advantage than I could by my patented drier,but to better regulate the aerial currents necessary to carry off thevapor escaping from the boards while in the act of beymg dried.

I therefore claim- 1. In the card-board drier as described, the buildingas constructed with the openings E in its side, in combination with thecard-.board carrier G, constructed with the drawer fronts or boards b toclose such openings.

2. I also claim the heating-pipes as arranged to extend both above andbelow such carrier Gr, and across it, and through its supportingframe F,all being substantially as shown and described.
